I spent a happy chunk of today designing and printing a front sensor assembly for the Hull PixelBot. The new part provides an ultrasonic distance measure and three light sensors.

This will mean that the robot will be able to find and move towards light sources and also detect obstacles in its path.

You can find out more about HullPixelBot at the next C4DI hardware meetup on Thursday 18th August. Sign up here (it's free). Anyone can come along and get into building tiny cheap robots. I'll have some more chassis kits to give away. All you need to do is add around 10 pounds worth of parts and you have a wandering pixel bot.
